Be it known that I, CHARLES G1; Donny, a citizen. of the United States, residing in the borough of Brooklyn, in the city and State of New York, have invented certain new and useful Improvements 1n Sample Cases, of wh ch the, following is a. specification..

My invention relates to .sample cases.

which are provided; with: sliding drawers,

and it consists: in certain improvements whereby the movement ofv the drawers is made to open and close their coiiperating doors, as is hereinafter. pointed. out and claimed.

In the drawings Figure 1 isfa side elevation,.partly in section-,,of-. a case embodying my improvements; Fig.2.is a crosssectional view, taken on the line 11 of. Fig. 1,. Fig. 3 is aplan view of the sliding track frame, Fig. 4 is a" sectional detail showing the connection between the drawer, sliding-a track frame and case; andFig; 5.-is a; detail, on an enlarged scale showing; the; hinge; connection between the case door and its follower and a, special door stop.

In all the figures the same reference letters designate the same parts.

The case 2 is divided into compartments, in the usual manner, and is provided with suitable guides or rails 3 to support the drawers 4, 4.

A sliding track frame is formed of two parallel rails 5, 5, which slide on the rails 3, 3, and are held thereupon by the undergripping ends of the cross bars 6, 6. The movement of the track frame is facilitated by antifriotion rollers 7 7 in the front cross bars of the case. The track-frame rails 5, 5, are, also, provided near their forward ends with antifriction rollers 8, 8, and with spring stops 9, 9, which normally stand out, as shown in Fig. 2, so as to prevent the undercut blocks 10, 10 on the bottom of the drawers 4, 4, from being slid out from the rabbets 11, 11 in the lower sides of the trackframe rails 5, 5. But, when these spring stops 9, 9, are pressed against their respective rails, the blocks 10, 10, may be drawn off the front ends of the traclcframe. The forward cross-bar 6 will engage with the front cross-bar of the case to stop the forward movement of the track-frame, and a suitable stop, as 12, engaging with the drawer causes the track frame to be carried back into the case with the drawer. It will be seen that thisarrangement provides an extended support for the drawer, to which fit is normally secured, and in cooperation with. which. it may be slid in and out with very little friction The sides of the drawers are inclined, at

their front ends, preferably on. a curve, as

shown: at 13; the front end of the drawer bottom? is provided; with a backward slope 14; and. the. upper edges of the. sides carry oogged. tracks. 15,. 15', into which mesl f toothed gears 16, 16 attached: to the inner sides-of the case. These. gear wheels 16, 16

are; preferably provided with ball-bearings, and' they may conveniently be mounted between. bars 17, 1 7, between which are also mounted. antifriction. rollers 18,- 18, which may be grooved, as shown, soas: to straddle the tracks 15, 15, and. 19, .1-9,- and ,bear against the smooth, margins of the latter, outside of. the cogs. Butstationary bear.- .ingsror. a.-smooth track may be provided insteadzof-the. roller bearings, 18, 18, if desired; The. doors 20,20; are. provided with sloping lower edges, 21, 21, to coiiperate fwitli theinclined drawer ends 14,14; andto their. backs are secured the tracks 19, 1'9, iwhicli mesh with the gear wheels 16, 16.

These doors are hinged to followers 22, 22, which serve to guide and steady the movements of the doors, so as to prevent tarving and binding, and also to carry the part of the tracks 19, 19 which remains in engagement with the gear wheels 16, 16, whenthe doors are closed. It will be seen that this guiding movement will be conveniently accomplished by plain extensions of the tracks 19, 19 running in the grooves of the wheel 18, 18. But any other suitable system of guides may be used.

Spring stops 24, 24, similar to the spring stops 9, 9, are attached to the sides of the case, and are adapted to engage in recesses 25, 25 in the edges of the follower, so as to stop its forward movement. Holes 26, 26 openthrough the sides of the follower behind the spring stops 24, 24; and by inserting pins or rods through these holes the springs may be depressed so that the follower may be drawn forward out of the case.

The operation of my device is as follows: When the drawer is slid back and the door closed, as shown in the second compartment from the top in Fig. 1, if it is desired to open the case, the drawer is grasped by the handle 23 and drawn forward, sliding over with it the follower 22 and the door 20.. And this movement may be continued until the parts reach the position shown in theupper portion of Fig. 1, when the gear,

wheels 16, 16 will be at the end of the tracks 15, 15; and, if it is desired to do so, the spring stops 9, 9 may be pressed in, and the drawer entirely detached from the case. The case is closed by pushing in the drawer; which causes the cogged wheels 16, 16, to

draw forward the door and follower, until the tracks 15, 15 have passed under the cogged wheels, when the follower will be in substantially the position shown in the second compartment from the top of Fig. 1, and the door will be resting upon the forward edges of the drawer. The door will then swing in, as the drawer is pushed back, and it will finally close into the position shown in the second compartment, in Fig. 1, the inclined edges, "of the door and of the drawer cooperating to make a locking joint.

In Fig. 5 I have shown the gear wheel 16 as set farther back from the front of the case than in the other figures; and a door stop 27 as placed in front of it, so that when the door is closed the stop 27 will prevent the door and its follower from being accidentally pushed back into the case. When the gear wheels 16, 16 are set forward as shown in Fig. 1 they act as door stops. But under some circumstances it may be preferable to use separate stops, as 27.

Having thus described my invention, what I claim and desire to secure by Letters Patent of the United States is The combination, with a samplecase frame, of a drawer provided with a projecting, transversely grooved bottom and sides backwardly curved at their forward ends and with cogged racks along their upper edges, a cogged wheel adapted to mesh above each of said racks, a sliding door-guide provided at eachside with a section of cogged rack adapted to engage above one of said cogged wheels, a downwardly swinging door hinged to the forward end of said doorguide and provided with a backwardly and downwardly beveled lower edge to engage in said transverse bottom groove, and also provided at each side with a section of cogged rack adapted to engage above one of said cogged wheels.
